Nuscale Power Corp
A designer of small modular nuclear reactors, NuScale makes compact, factory-built power units called NuScale Power Modules that utilities can group together to generate electricity and heat for homes and industry. The technology was born in the labs of Oregon State University, where engineer José Reyes studied a reactor that cools itself by natural circulation rather than pumps; he and Paul Lorenzini spun it out into a company in 2007. The name "NuScale" plays on that "nuclear, scaled down" idea — its reactors are roughly one-hundredth the size of a traditional nuclear plant.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 3 years: -128.78M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
